IMPROVEMENT IN ELECTRO-MAGNETIC ENGINES.

Specification forming part of Letters Patent No.7 ,287, dated April 16,1850.

To all whom it may concern.-

Be it known that I, JOHN H. LILLTE, of Joliet, inthe county of Will andState ofIllinois, have invented a new and useful Machine forElectro-Magnetic Power; and I do hereby declare that the following is afull, clear, and exact description of the principle or character whichdistinguishes it from all other things before known, and of the usualmanner of making, modifying, and using the same, reference being had tothe accompanying drawings, in Which- Fignre 1 is a top plan. Fig. 2 is abottom plan. Fig. Sis a side elevation.

My invention consists inthe employmentof a number ot' permanenthorseshoe-magnets, compound or single, revolving` on a wheel in front ofan electro magnet or magnets fixed stationary to the frame; and inconjunction therewith I-employ a helix of tine wire around scribed..

The construction of the apparatus is as follows: A series of any givennumber of permanent 'compound -or single U magnets, a, are placed in awheel, b, properly constructed for the purpose, in a radial positiomwiththeir poles project-ing a little beyond the periphery of the wheel, asclearly shown in the drawings. Onone end of the axis of this -wheelthere is a large spur-wheel, c, which drives two pinions, d, to whichthe brake-pieces are attached, to be more particularly describedhereinafter.

The frame on which the wheel is supported serves to hold twoelectro-magnets, or more, as the case requires. vThese electro-magnets eare on a line radial fromV the shaft, one on each side, and areconstructed in any ot' the Well-known waysof U`-formed electro-magnets.Around the coils upon these magnets are iine wires f. (Represented byred lines, the blue lines being the wires of the magnet.) Thesesecondary coils f are connected with electro-magnets g, placed below, asseen in the drawings, Where they form a circuit and cause the`electro-magnets gto be magnetized by means of this arrangement, and forthe purpose also of destroying the secondary currents. These magnets areso placed. as to aid in the propulsion ofthe wheel, the coilf from theelectro-magnet ev on one side being con: nected with the secondarymagnet g on the 0pposite side, as clearly shown in the drawings.

The break-piece h la' is formed of two parts, one half of which, h, is anon-conductor, the other half, h', a conductor, connected by means of a.spring, fi, with the opposite cut-ofi" shaft in such a way as to bethrown alternately onto one or the other of two insulated break-pieces,7c lo', by which the current is nia-de to pass in one direction or theother through either of the coils. One of these break-pieces, k, isconnected with the battery by means of the springl through thebinding-screw on. The

other break-piece, k', is connected with the opposite binding-screw,n,`by the spring u. One end of each of the two primary blue coils areconnected by the wire o with the break-piece or current-changer 7c 7c bymeans of the spring o. The other ends of thesev coils are alter- Inatelyconnected with the springt to close the current by means of thewires pand qand The auxiliary electro-magnets are aids to the main ones,andtheir action is too apparent on an inspection of the drawings to requirefurther description.

Having thus fully described my. improvements in electro-magneticmachinery, what' I claim therein as new, and for which I desire tosecure Letters Patent, is

1. The employment of induced electricity as above stated in producingmagnetism in the secondaryelectro-magnets, to be used as a motive powerin. connection with the prime mover, and to neutralize -the secondarycnrrents of the principal magnets formed by the direct current from thebattery.

2. The combination of the magnet-changer h h and pole-changer .lc 7a',substantially in the manner and for the purpose set forth.
